The RSF Series Metal Oxide Film Flame-Proof
Resistors offer excellent performance in
applications where stability and uniformity of
characteristics are desired. They provide lower
cost alternatives to Carbon Composition
Resistors and General Purpose Metal Films.
Metal Oxides also can replace many low power
General Purpose wirewound applications, saving
both money and time, with shorter delivery
cycles. The normal style & ‘RSF-WV’ style of
RSF series are coated with layers of gray flame-
proof lacquer, and the miniature style except
‘RSF-WV’ style are coated with layers of pink
colors flame-proof lacquer.
